Abstract: In order to improve the lubrication performance of the slipper/swash plate pair on axial piston pump, the
elliptical micro-pits texture was constructed on the swash plate based on the bionics principle. The effect of dynamic
pressure and upstream pumping were generated by the elliptical micro-pits, and it can be used to optimize the friction
performance of the slipper/swash plate pair and reduce the leakage. Based on the CFD method, the modeling and
lubrication performance of the slipper/swash plate pair were carried out with the elliptical micro-pit texture. It was
revealed that the carrying capacity, leakage and friction coefficient of the slipper/swash plate pair changed with variation
of the tilt angle of micro-pit under different speed and different viscosity of the lubricant. The results showed that the
carrying capacity of the slipper/swash plate pair was significantly improved, and the friction coefficient decreased, but
the leakage increased after establishing a non-inclined elliptical micro-pit on the swash plate. Spinning a certain angle
with respect to its sliding direction reduced the amount of leakage mostly while the carrying capacity and friction
coefficient of the slipper/swash plate pair remained stable.
Key words: slipper/swash-plate pair; upstream pumping; fluid dynamic lubrication; texture; inclined-ellipse-dimple
